I used it for the first time last weekend in a 1000 ftÂ² room. 70 persons.
I had already used the magnum 2000.
Pro: easy setup
pro: fog dispersion
Pro: almost nonstop use possible! (short warm up time)
Con: no fixation arch like on the 550
Con: no DMX control!
I filled the whole room with fog during 4 or 5 hours with only one 10 cl ZR Pro container!!
So it's almost impossible to empty the 1 liter tank of the machine!
I strongly recommend this machine!
Amazing value for money. It has no disadvantages except for the lack of DMX control...
